Hair Growth For Men

Hello, I had a hair transplant two months ago and I really don’t know how does the hair transplant after operation procedure and where I went to have a surgery , after they didnt so much explained to me how will it be. For example, how many months later I will have my hair ? etc. So it has been just two months but do you have an idea that how is the hair growth for men ? how many months later? Should I use my regular shampoo? what is the general time for hair growth for men?
